Metallic coatings provide a layer that changes the surface properties of the workpiece to those of the metal being applied. The workpiece becomes a composite material exhibiting properties generally not achievable by either material if used alone.

Vapor blasting uses water with media which is recycled around the machine. The water buffers the media when it hits the component giving a smooth finish, especially on stainless steel and aluminium, without damaging the metal.

Peening is the process of working a metal’s surface to improve its material properties. Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses. Depending on the part geometry, part material, shot material, shot quality, shot intensity, and shot coverage, shot peening can increase fatigue life up to 1000%.
